Benign Tumors

A benign tumour is a growth that is not cancerous — it doesn't invade surrounding tissue or spread to distant parts of the body. Benign tumours are very common; most cause no problems and are simply watched. Some need treatment because of their size, location, appearance, or symptoms.

Common examples

• Lipomas — soft fatty lumps under the skin.
• Skin tags, moles, haemangiomas, seborrhoeic keratoses.
• Breast fibroadenoma — mobile rubbery lump in young women.
• Uterine fibroids.
• Thyroid nodules, adrenal adenomas, pituitary adenomas — usually non-cancerous but can affect hormone function.
• Pleomorphic adenoma — commonest parotid gland tumour.
• Colon polyps (adenomas) — benign but some can turn cancerous over years.
• Meningiomas, schwannomas, acoustic neuromas — nervous-system tumours.

When a benign tumour needs attention

• Grows rapidly.
• Causes pain, pressure or blockage symptoms.
• Bleeds, ulcerates, or changes in appearance.
• Produces too much of a hormone (pituitary, adrenal, thyroid).
• Cosmetic or psychological concern.
• In a location where a "benign-looking" lump could actually be cancer — for these, biopsy is important.

"Benign" doesn't always mean "leave alone"

• Some benign tumours can become cancerous over time — colon polyps, certain skin lesions, neurofibromatosis-related tumours. Surveillance matters.
• Some benign tumours cause symptoms like cancer — e.g. a meningioma pressing on the brain can cause seizures or weakness.
• Diagnosis matters — imaging + biopsy confirms; don't assume anything is benign without evaluation.

An accurate diagnosis is the single most useful thing — sometimes it means reassurance, sometimes it means a small procedure, rarely it changes the picture entirely. A Health Expert can help you decide what needs watching, what needs removing, and what can be left alone.
